hattab fethi Posted March 7, 2006 Report Posted March 7, 2006 I have documents which explains the protocol ppi (explains the formats of frame accepted by the CPU of the S7-200 automat). I wrote a code which ensures the communication between PC and s7-200. I tested but it does not function I have make several checking: - I have an achievable file which ensures the communication between PC s7-200. I used a serial monitor to know the frame exchanged between PC and automat I noted that they similar to those are used in my code I have doubts about times (use of structure COMMTIMEOUTS) typedef struct _COMMTIMEOUTS { // ctmo DWORD ReadIntervalTimeout; DWORD ReadTotalTimeoutMultiplier; DWORD ReadTotalTimeoutConstant; DWORD WriteTotalTimeoutMultiplier; DWORD WriteTotalTimeoutConstant; } COMMTIMEOUTS,*LPCOMMTIMEOUTS; language used is C++ if you have in more one idea on others problémes which can met us. To indicate us Doc1.doc Please help me Quote
